An Alternative Numerical Solution to a Screw-Thread Problem Using Displacement-Potential Approach

摘要

An alternative numerical solution to a screw-thread problem is presented. A displacement-potential-based computational scheme is developed to model the physical conditions and the arbitrary shape of the screw-thread geometry, wherein the principle of linear interpolation is used to transfer the boundary values at the non-nodal boundary points to neighboring field nodal points. The elastic field of a Buttress thread is analyzed to obtain the distributions of displacements and stresses over its normal cross-sections. The solutions are then compared and discussed in light of those obtained by analytical as well as standard computational approaches.View full textDownload full textKeywordsAlternative solution, Screw thread, Arbitrary boundary shape, Linear interpolation, Displacement potentialRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/15502287.2012.682195
